Question

我正在尝试使用手掌位置来获取距离传感器原点（表面）的手距离，然后将其用于我编写的函数中，该函数比较一组边界内的位置（每个轴一个）来计算来自传感器的数据的权重，因为内置在飞跃API中的“置信度”变量非常糟糕。

问题在于，无论何时我转过头，轴似乎都会改变，这完全是我的范围。有没有办法可以中和旋转，使轴保持一致，即Z远离传感器，X左右，Y上下。如果我面向前方它完美地工作，因为轴是如此详细，但如果我看起来正确，它就消失了。：（

我将不胜感激。

FYI - 传入的参数'position'是手掌位置。

 float CalculateSensorWeight(Vector position)
    {
        float HighestX = 1f, LowestX = -1f;
        float HighestY = 1.2f, LowestY = 0.6f;
        float HighestZ = 1f, LowestZ = 0.4f;

        HighestX *= transform.root.lossyScale.x;
        LowestX *= transform.root.lossyScale.x;
        HighestY *= transform.root.lossyScale.x;
        LowestY *= transform.root.lossyScale.x;
        HighestZ *= transform.root.lossyScale.x;
        LowestZ *= transform.root.lossyScale.x;

        Debug.Log(position);

        clampedX = (1f - (-1f)) / (HighestX - LowestX) * (position.ToVector3().x - HighestX) + 1f;
        clampedY = (1f - (-1f)) / (HighestY - LowestY) * (position.ToVector3().y - HighestY) + 1f;
        clampedZ = (1f - (-1f)) / (HighestZ - LowestZ) * (position.ToVector3().z - HighestZ) + 1f;

        totalClamp = clampedX + clampedY + clampedZ;

        //Debug.Log(clampedX + " , " + clampedY + " , " + clampedZ + " = " + totalClamp);

        float weight = (1f - 0f) / (3f - (-3f)) * (totalClamp - 3f) + 1f;
        weight = ((weight-0f)/(1f-0f))*(1f-(-1f))+(-1f);
        weight = 1f - Mathf.Abs(weight);

        //Debug.Log("Weight = " + weight);
        //Round the weight to 2 decimal places for asthetics and ease
        weight = Round(weight, 2);
        return weight;
    }
